CORNBSHELLER?.

SPECIFICATION forming part of Letters Patent No. 299,136, dated May 27,1884.

Application filed March 1, 1884. (No model.)

To aZZ whom it may concern,.-

Be it known that I, Janus M. HiiwLnY, a citizen of the United States,residing at Odin, in the county of Marion and State of Illinois, haveinvented a new and useful CoruSheller, of which the following is aspecification, reference being had to the accompanying drawings.

This invention has relation to hand cornshellers; and it consists in theconstruction and novel arrangement of parts, as will be hereinafterfully described, and particularly pointed out in the claims appended.

Figure lis a front elevation of a hand corn- Sheller embodying theimprovements of my invention.` Fig. 2 is avertical sectional view on theline x x in Fig. l. Fig. 3 is a rear elevation; and Fig. 4 is ahorizontal sectional view on the line y y in Fig. l.

Referring by letter to the accompanying drawings, a designates thecast-iron standard of the machine, consisting of the perforatedbase-lugs a a', through which the securing screws are passed into thebench or other place of support, from which rise the inwardly-inclinedlegs a2 ai, connected at their lower ends by the crossbar a3, andsurmounted by the annular vertical rim a4, the whole being cast in asingle piece. An annular shell, b, is provided at its rear edge with averticallyarranged annular flange, b,which is provided at one edge witha crank-arm, b2, having a handle, b, near its end.` The annular shell bhas a portion cut away at its front edge, which leaves a space, b", andat the middle of the space b a projection, b, triangular in plan view,extends forward from the metal of the shell b into the space b, for apurpose hereinafter explained. This annular shell I), its rear flange,the crank-arm, and projection (l5 are also cast integral. The annularshell b fits into and turns in the ,vertical annular rim a", which formsits bearing when the machine is operated. Alat casting or plate, c, isprovided in its upper portion with an opening, c2, bounded by an annularrim, c, which slips upon the annular shell b when in position, and isheld in place by a pin, 0*, passed through a perforation, c5, in theannular shell b, as one fastening, and further by a key, c, which fitsin a recess, c7, in a curved projecting rib, cs, cast upon the annularrim, front side, above the opening c in the plate c, said key c pressing against the outer face of the triangularshaped projection b5 tocause the plate c to rotate with the shell b when the machine isoperated. The casting or plate c is provided with a laterally-extendingflange,A cw, at its straight end,which is provided at its ends withlaterally-projecting perforated lugs d d, and above these the straightsides ofthe casting c are provided with other laterally-projecting lugsclcl, also perforated. These four lugs are on the front face of thecasting 0, and the casting, its iiange, its curved projecting rib, andits lateral lugs are all cast integral, as is also the crank-handle d2upon the under edge of the flange C10-21 e., the under edge-when the machine is in its normal position-viz., at rest.

The arms c e, which carry the shelling-jaws e c at their upper ends, areprovided at their lower ends with short integral arms e3 c3 at rightangles to the arms c c, and extending toward the outer edges of thecasting c'. These arms e c e3 c3 are securedto the horizontal flange cwby pivot-bolts e* e". The shellingjaws c c are semicircular in verticalsection, and are provided with two teeth, e5 c, each, by which the cornis removed from the cob. The inner faces of the curved jaws e c are pro-4vided with two or more diagonal and oppositely-inclined cutting-ribs orscrew-threads, e7 el c es, cast solid therewith, which, when the machineis operated, are pressed into the corn-cob, and cause it to travelthrough the jaws at a uniform speed. The outer ends of the short armse:s e3 are provided, near their outer ends, with perforations, which areinline with the perforations of lthe lugs above and below them. Throughthese perforations, one at each side of the casting c, are passedloosely spring-rods f f, threaded near their upper and lower ends forthe reception Iof nutsf"ff2f2, the former being below the upper lugs,and the latter below the lower lugs, as shown.

Around the spring-1odsff,and between the upper nuts,'ff, and the upperfaces of the short arms e3 ci are the spiral tension-springs g g, bywhich the compression-power is iniparted to the shellingjaws throughtheir arms, to cause them to remove the corn from the cob. The tensionof the springs is regulated by tightening or loosening these nuts sothat the jaws may be fitted to all sizes of ears of corn from thelargcstto the smallest size.

IOO

In order to prevent lateral or vertical strain upon the pivot-bolts e4e4, I provide a crossbar, h, in front of the arms e e, and this bar issecured by rivets h h', passed through it and into the annular shell'b.The triangular projection b5, when the cob has been removed, stops thejaws always in the center of the annular shell b.

The operation of the :machine is very simple, and is as follows: The earof corn is entered between the shelling-j aws from the rear side, and isheld by one hand, while the other hand is used to turn one of thecranks, of which there are two, until the corn has been shelled forone-half or more of the length of the cob, when the other hand is usedto hold the cob, and the hand that formerly held the ear is used to turnthe other crank until the cob passes through the jaws from the rear tothe front.

rlhe advantages of the invention are numerous. It is light, cheap, anddurable. It possesses great speed, is simple in construction, and willnot get out of order. It is neat and attractive in appearance, and isefficient for the purposes for which it is intended.

Having thus fully described my invention, what I claim as new, anddesire t secure by Letters Patent of the United States, is-

1. In a hand corn-Sheller, the annular shell b, provided with thecut-away portion b4, the central triangular projection, b5, the rearflange, b', and the crank-arm b2, all cast in one piece, substantiallyas specified.

2. In a hand corn-Sheller, the flat plate or casting c, provided withthe opening c`l in its upper portion, surrounded by the annular rim c3,provided with the curved projecting rib 'c8 above the lower opening, c,the lugs d d', horizontal flange c, and cranlr-handled2,all cast in onepiece, substantially as specified.

3. In a hand corn-Sheller, the combination of the standards a2 a2,having the vertical annular rim a4, the annular shell b, having thecut-away portion b"g and the triangular proj ection b5, the cross-bar hover the space b4, the rear flange, b', and the crank-handle b2, and theflat casting c, having the openings c2 for the annular shell b, theprojecting rib cs, perforated lugs d d', the shelling-jaws e e', the parms e e, and perforated angular extensions e3 e3' at their lower ends,the spring-rods f f, springs g g, and regulating-nuts f f2,substantially as specilied.

4. In a hand corn-sheller, the combination, with the flat casting havingthe openings cz for the annular shell b, and the perforated lugs d d onits front face,of the pivoted angular arms e e e3 e3, carrying theshelling-jaws at their upper ends, the spring-rods, spiral springs, andregulating-nuts, substantially as specied. K

5. In a hand corn-Sheller, the combination, with the pivoted angulararms e e e3 e3, the casting c, having the horizontal iiange al", thespring-rods, spiral springs, and regulatingnuts, of the curvedshelling-jaws provided with two teeth, e5 e, each, and provided on theirinner faces, and cast solid therewith, with two. screw-threads, e7 es,arranged diagonally of the jaw-faces and in directions opposite onopposite faces, substantially as specied. 6'. In a hand cornsheller, thecombination, with the pivoted angular arms e e e3 e3, carrying theshelling-jaws e e', of the standards c2 a2, flat casting c, and theannular shell b, provided with the triangular projection b5 between thepivoted arms, substantially as specified.

' In testimony that I claim the foregoing as my own I have heretoaffixed my signature in presence of two witnesses.
